flange (1).
4. Apply anti-corrosion oil to the thread and seat of new drive pin- ion lock nut, and temporarily tighten drive pinion lock nut to drive
pinion.
CAUTION:
Do not reuse drive pinion lock nut.
5. Tighten to drive pinion lock nut, while adjust total preload torque.
CAUTION:
Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.
After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.
If measured value is out of the specification, remove final
drive assembly and disassemble drive pinion parts to check
and adjust each part. Refer to FFD-13, "
Removal and Installa-
tion (VQ35DE Models)" ,FFD-15, "Removal and Installation (VK45DE Models)" and FFD-17, "Disas-
sembly and Assembly" .
6. Install front propeller shaft. Refer to PR-5, "
Removal and Installation" .
7. Install side shaft assembly.
8. Install front drive shaft both. Refer to FAX-12, "
Removal and Installation (Left Side)" , FAX-13, "Removal
and Installation (Right Side)" .
9. Refill gear oil to the final drive and check oil level. Refer to FFD-8, "
FILLING" .
10. Check the final drive for oil leakage. Refer to FFD-8, "
OIL LEAKAGE AND OIL LEVEL" .

10. Install companion flange (1). NOTE:
When reusing drive pinion, align the matching mark (B) of drive
pinion with the matching mark (A) of companion flange, and then
install companion flange (1).
11. Apply anti-corrosion oil to the thread and seat of new drive pin- ion lock nut, and temporarily tighten drive pinion lock nut to drive
pinion.
CAUTION:
Do not reuse drive pinion lock nut.
12. Tighten to drive pinion lock nut, while adjust pinion bearing pre- load torque.
CAUTION:
Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.
After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.
13. Install differential case assembly. Refer to FFD-34, "
Differential
Assembly" .
CAUTION:
Do not install carrier cover yet.
14. Check and adjust drive gear runout, tooth contact, drive gear to drive pinion backlash, and companion flange runout. Refer to FFD-21, "
Drive Gear Runout" , FFD-21, "Tooth Contact" , FFD-23, "Backlash" ,
FFD-23, "
Companion Flange Runout" .
Recheck above items. Readjust the above description, if necessary.
15. Check total preload torque. Refer to FFD-20, "
Total Preload Torque" .
16. Install carrier cover. Refer to FFD-24, "
Differential Assembly" .
Differential Assembly
1. Install side gear thrust washers with the same thickness as the
ones installed prior to disassembly or reinstall the old ones on
the side gears.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
Revision: 2006 December 2006 FX35/FX45
TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

FRONT FOG LAMP
Revision: 2006 December 2006 FX35/FX45
Aiming AdjustmentNKS002X9
Front fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.
Keep all tires inflated to correct pressure.
Place vehicle on level ground.
See that vehicle is unloaded (except for full levels of coolant, engine oil and fuel, and spare tire, jack, and
tools). Have the driver or equivalent weight placed in driver seat.
Adjust aiming in the vertical direction by turning adjusting screw.
1. Set the distance between the screen and the center of front fog lamp lens as shown at left.
2. Turn front fog lamps ON.
3. Adjust front fog lamps using adjusting screw so that the top edge of the high intensity zone is 100 mm (3.94 in) below the height of
front fog lamp centers as shown at left.
When performing adjustment, if necessary, cover headlamps
and opposite front fog lamp.

TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. Trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. Rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.
